Sensitivity problems with rapid antigen tests are also helping the more accurate rapid molecular tests gain wider acceptance, manufacturers said.

The test  runs on the GeneSTAT system, and has demonstrated 100 percent sensitivity, 99.6 percent specificity, and 100 percent reproducibility. 

The firm said that its platform successfully detected pathogens and resistance markers at limits of detection as low as 1 CFU/ml in spiked blood samples.

Using a blood volume of 100 μL, the test demonstrated a sensitivity of 90.2 percent for the diagnosis of blood-culture positive sepsis episodes.

Researchers from France's Gustave Roussy Institute designed EGFR mutation assays for the system, which they showed could be useful for testing in non-small cell lung cancer patients.

The test, which is currently for research use only, uses fluorescent multiplex PCR to co-amplify seven markers for analysis of the MSI-high phenotype.

The agreement with Mexico's agriculture department covers studies to evaluate molecular detection assays for bovine TB, as well as studies on zoonotic TB diagnosis.

PerkinElmer's subsidiary Wallac will now distribute the Amplidiag product line in Israel and in a number of countries in Africa.

While point-of-care molecular testing of patients with respiratory illness wasn't associated with lower antibiotic use, patients tested had shorter drug courses.

The firm is now launching the test in Europe, supported by results from a multicenter prospective study showing high sensitivity in detecting bladder cancer.
